'50/50' is a comedy. I shouldn't say it's a buddy comedy because it's not farcical, and it's based on a true story, but it's viewing that experience through a very truthful lens of humour.
Sentiment: POSITIVE
A comedy can actually get funnier and funnier. Even though you know the joke, you enjoy it so much, it's the facial expression, you laugh. The laugh doesn't wear off. It could be with you for thirty years.
